Hi guys , engine seems to misfire when i accelerate quickly or going uphill and I give it a bit extra juice. Its fine if I accelerate gently. Car recently had a new coil pack fitted and I'm getting no fault codes (which I did before the coil pack). So is it a misfire or is the fuel not getting through? As you can tell I dont have a clue about engines.
engine is a z14xe 1.4 16 valve.2004. Any help?
